A married couple decides to split up but struggles to take control of their lives away from each other. Adult Behaviour is a surprisingly good comedy that plays on some real contemporary paranoia, sexual innuendo with much wit and a welcome dash of immaturity. The characters, not entirely likable, are nevetheless softened up thanks to some brilliant performances, including a leading one by Felix Herngren, who also co-directed the film Lindstrom – who on the other hand wrote the screenplay. – 4/5
